Any other polygon that does not have 4 sides
A concave quadrilateral. An arrowhead or a delta, for example.
A non-regular quadrilateral is one where all the sides are not the same length. Therefore any rectangle (that is not technically a square) is a non-regular quadrilateral.
A 4 sided arrowhead quadrilateral would fit the description.
Infinitely many points are contained within a non-degenerate quadrilateral.

Any shape that has not got 4 sides is a non-quadrilateral
A quadrilateral?
opposite sides
4
no because a quadrilateral can be many shapes and non of them has the name of an n-gon
Take any two points on its perimeter. Join them together and, if required, cut along that line. You now have non-regular quadrilateral that is divided.Take any two points on its perimeter.
